STUDY ON ASEISMIC SUSPENSION CEILING WITH STEEL FURRINGS

Collapse damages of suspended ceilings during recent severe earthquakes are focused as mentioned in references 3), 6). In order to establish aseismic design method of suspended ceiling, static lateral loading tests are conducted for both conventional and grid system ceilings that are partial models made of real components. Newly developed aseismic stiffeners are applied in the models and their availabilities are confirmed through the tests. Finally, evaluation formulas of buckling strength, which are based on Euler's formula, for combined bracing system are proposed.
